Ireland captain Porterfield vents his ire over DRS

Ireland captain William Porterfield was left fuming at Sri Lankan umpire Asoka de Silva's decision to give Gary Wilson out lbw despite replays showing that he had offered a shot to a delivery that appeared to hit him outside the line of off-stump.

The ICC was again prompt in reprimanding the Irish captain for publicly venting his ire.

Former Australian test umpire Darrell Hair is also sceptical about the possible overuse of technology.

"I cannot help wondering how much of a confidence dent will be left on some of our ICC umpires when they begin to continually have decisions overturned," he wrote in the journal of the New South Wales Cricket Umpires and Scorers Association.

Sri Lankan de Silva, one of the elite panel umpires, has already paid the price after a poor tournament and did not feature in any role in the ICC list for the quarter-finals.

Both the system and the umpires are bound to come under further scrutiny when business end of the tournament kicks off on Wednesday.
